EPC has announced the EPC2221, a common source dual gallium nitride (GaN) FET rated at 100 V, 58 mΩ, and 20 A pulsed current. The integrated circuit is designed to be used in lidar systems for robots, surveillance systems, drones, autonomous cars, and vacuum cleaners.
EPC said the low inductance and capacitance of the EPC2221 allows fast switching (100 MHz) and narrow pulse widths (2 ns) for high resolution and high efficiency. In addition, the small size of 1.35 mm by 1.35 mm reduces PCB cost and the total solution size, EPC said.
The EPC2221 is the latest addition to the company’s family of GaN transistors and integrated circuits designed to meet performance and reliability standards of automotive applications. EPC said the 2221 has completed automotive AEC Q101 qualification testing, including humidity testing with bias (H3TRB), high temperature reverse bias (HTRB), high temperature gate bias (HTGB), and temperature cycling (TC), as well as other tests.
In addition to lidar for automotive applications, EPC said the 2221 is also well suited for high-frequency DC-DC conversion, wireless power applications, and synchronous rectification.
“This new AEC certified product is the latest addition to a growing family of EPC gallium nitride-based transistors and integrated circuits designed to enable autonomous driving and improve safety,” said Alex Lidow, CEO and co-founder of EPC. “This new integrated circuit improves the performance while reducing size and cost for time-of-flight lidar systems.”
The EPC2221 costs $1.26 for a 2.5Ku reel, and available for immediate delivery from Digi-Key Electronics here. The company also offers a cross reference tool for designers that are interested in replacing silicon MOSFETs with a GaN solution.
